Php 当表单是循环且只有一个提交按钮时，如何获得一组单选按钮的不同值？

学校项目：投票系统

你能告诉我怎样才能得到表单中每个循环的radion按钮“被提名者”的值吗。在每种形式中，选民只应投票给候选人中的一位，例如总统候选人。我如何只需一个提交按钮就可以获得每个职位（总裁、副总裁等）的投票

代码如下：

<?php

$readPos = new Voting();
$rtnReadPos = $readPos->READ_POSITION($org);
?>
<div class="container">
<div class="row">
    <?php if($rtnReadPos) { ?>
    <div class="col-md-6 col-md-offset-3">
        <?php
        if(isset($_POST['vote'])) {
            $org            = trim($_POST['org']);
            $pos            = trim($_POST['pos']);
            $candidate_id   = trim($_POST['nominee']);
            $voters_id       = trim($_POST['voter_id']);


            $insertVote = new Voting();
            $rtnInsertVote = $insertVote->VOTE_NOMINEE($org, $pos, $candidate_id, $voters_id);
        }
?>
        <div class="voting-con">

            <br><h4 style="text-align: center;"><?php echo $org; ?> Voting Page</h4><hr />
            <?php while($rowPos = $rtnReadPos->fetch_assoc()) { ?>
            <form action="<?php $_SERVER['PHP_SELF']; ?>" method="POST" role="form">
                <p class="help-block"><b><?php echo $rowPos['pos']; ?></b></p>
                    <?php
                    $readNominee = new Voting();
                    $rtnReadNominee = $readNominee->READ_NOMINEES($org, $rowPos['pos']);
                    ?>

                    <?php if($rtnReadNominee) { ?>
                        <div class="form-group">
                        <?php while($rowNominee = $rtnReadNominee->fetch_assoc()) { ?>
                        <input class="form-control" type="radio" name="nominee" value="<?php echo $rowNominee['id']; ?>"><?php echo $rowNominee['name']; ?> </input><br>

                                <?php } //End while ?>
                            <!-- <select name="nominee" class="form-control"> 
                                <option value="">*****Select Nominee*****</option>
                                <?php while($rowNominee = $rtnReadNominee->fetch_assoc()) { ?>
                                <option value="<?php echo $rowNominee['id']; ?>"><?php echo $rowNominee['name']; ?></option>
                                <?php } //End while ?> 
                            </select>-->
                        </div>                      
                    <?php } //End if ?>
                    <input type="hidden" name="org" value="<?php echo $org; ?>">
                    <input type="hidden" name="pos" value="<?php echo $rowPos['pos']; ?>">
                    <input type="hidden" name="voter_id" value="<?php echo $_SESSION['ID']; ?>">

                <?php
                $validateVote = new Voting();
                $rtnValVote = $validateVote->VALIDATE_VOTE($org, $rowPos['pos'], $_SESSION['ID'])
                ?>

            <hr />
            <?php } //End while ?>
            <button type="submit" name="vote"
                            <?php if($rtnValVote->num_rows > 0) { ?>
                            <?php echo "class='btn btn-default disabled'>"; ?>
                            <?php } else { ?>
                            <?php echo "class='btn btn-info'>"; ?>
                            <?php } //End if ?>
                        Vote
                    </button>
            </form>

        </div>
    </div>
    <?php } //End if ?>
